[JS CS6] paste onto active document from external .indd

Question

Hey everyone, i'm at a complete loss with this, tried loads of examples from this forum etc and cant get anywhere so i've given up!
All i'm trying to acheive is to prompt the user for a code, then that refrences an indesign file in a folder, this is all working ok, we have a variable called BMDFile with a full file path ready to go, but I can't figure out how to get this file on a currently open document in an editable format.
I just want it to paste from an indesign file onto this empty doc
I'm trying to edit this example from the forum now...
var doc1 = app.documents[1]; //  needs to be from an external .indd file (variable BMDFile already contains a full path)
var doc2 = app.documents[0];  // paste to
for(i=0; i<doc1.pages.length; i++)
    if(doc2.pages.length < i+1){
        doc2.pages.add();
    doc1.pages[i].pageItems.everyItem().duplicate(doc2.pages[i]);
Thanks in advance!

Unfortuately the Workflow setup here (that I cant change is)
Designer accepts a job for a customers ad with other software we use, it creates a blank indesign template with the correct name in the correct place with correct colour settings etc
It opens that blank document in InDesign and the designer makes the ad
Designer ends the job by using a script here (which I cant change) to Save (on top) & generate a PDF to specific settings
So unfortunately the 'current empty document' I'm looking to paste this external stuff onto, is a file that could be in various different folders and names, i can't see an easy way to script it.
I just wanted to script:
Designer has the automatic blank template up, sees its a repetative ad
Designer presses F4 (or similar for this script) types a code number
Script pastes the almost fully made ad on the template for them
If indesign cant do this, i'm probably better off scripting windows to find out where these files are saves and copy a pre-saved template into the relevant folder with the new name (if i can find out how its generated) and then open that.  But this means the designer would be shutting down a blank template, running a script then opening it, not very intuative.  I was thinking of a library but only one user can work on it at a time, so not ideal.  Placing a Snippet DOES work, leaving editable objects, but to update a snippet seems to be a lot of unnecessary clicks if it could just remain an .indd that anyone could go in and update as necessary
Before you think it, don't worry, i agree this companies workflow is akward at best, i'm just trying to save daily repetitive clicks, file browsing and copy & pasting for pretty simple templates.
